Often the people Pi met in Mendocino wanted to hear these terrible stories, the personal disasters, or they quoted them back to her from what they'd read, with a certain glitter in their eyes -- giving Pi the chance to wonder again as she once had in a Wittgenstein seminar why there wasn't a word in English for Schadenfreude, that very human pleasure taken in other people's misery.
--Sylvia Brownrigg, The Metaphysical Touch

Schadenfreude comes from the German, from Schaden, damage + Freude, joy. It is often capitalized, as it is in German.

Zählt wie Wanderlust, Zeitgeist und Weltschmerz zu den Worten, die kein exaktes Äquivalent im Englischen haben, und daher in der deutschen Form gebraucht werden: The Schadenfreude.
